Description
Die vorliegende Erfindung bezieht sich auf eine Vorrichtung und ein Verfahren zur Herstellung eines Wabenkörpers, insbesondere eines Katalysator-Trägerkörpers, aus wenigstens einem Stapel aus einer Vielzahl von zumindest teilweise strukturierten Blechen.The present invention relates to an apparatus and a method for producing a honeycomb body, in particular a catalyst carrier body, from at least one stack from a variety of at least partially structured sheets.
Zur Verringerung der Schadstoffmenge in Abgasen, insbesondere in Kraftfahrzeugabgasen, werden Katalysatoren verwendet. Die Trägerkörper in solchen Katalysatoren können in der Form von metallischen Wabenkörpern ausgebildet sein. Solche Wabenkörper umfassen einen Stapel aus einer Vielzahl von zumindest teilweise strukturierten Blechen. Durch die U.S.-A 4,923,109 ist ein Wabenkörper bekannt, der einen gegensinnig um sich selbst und um einen Zentralbereich verschlungenen Stapel aufweist.To reduce the amount of pollutants in exhaust gases, especially in motor vehicle exhaust gases, catalysts are used. The carrier body in Such catalysts can be in the form of metallic honeycombs be trained. Such honeycomb bodies comprise a stack of a plurality of at least partially structured sheets. By U.S.-A 4,923,109 a honeycomb body is known, which has an opposite direction itself and has a stack intertwined around a central area.
Ferner ist durch die WO 90/03220 ein metallischer Katalysator-Trägerkörper bekannt, der aus zumindest teilweise strukturierten Blechen aufgebaut ist. Dieser Katalysator-Trägerkörper umfaßt wenigstens drei Stapel von Blechen, wobei mindestens drei der Stapel um je eine zugehörige Knicklinie im Zentralbereich des Wabenkörpers gefaltet und im gefalteten Zustand gegensinnig umeinander und um einen Zentralbereich mit den Knicklinien verschlungen sind.Furthermore, WO 90/03220 is a metallic catalyst carrier body known, which is constructed from at least partially structured sheets. This catalyst carrier body comprises at least three stacks of sheets, whereby at least three of the stacks each have an associated crease line in the Central area of the honeycomb body folded and in the folded state in opposite directions entwined around each other and around a central area with the crease lines are.
Zur Herstellung solcher Wabenkörper sind Vorrichtungen bekannt, die eine um eine Achse verdrehbare, an jedem Stapel angreifende gabelförmige Umschlingungseinrichtung und sich zu einer Form schließende Formsegmente umfaßt. Die Innenkontur der geschlossenen Form entspricht der Außenkontur des Wabenkörpers im umschlungenen Zustand. Um ein Umschlingen der Stapel bzw. des Stapels um sich selbst und um einen Zentralbereich zu gewährleisten, werden die Formsegmente zum Stapel hin so bewegt, daß während der Drehung der gabelförmigen Verschlingungseinrichtung der Stapel bzw. die Stapel am Rand der Form segmente anliegen und dieser Rand ein Widerlager bildet. Gegen Ende des Herstellungsvorgangs wird die Form vollständig verschlossen und so dem Wabenkörper seine endgültige Form verliehen.Devices for producing such honeycomb bodies are known which have a fork-shaped, rotatable about an axis and engaging on each stack Wrapping device and form segments closing into a form includes. The inner contour of the closed shape corresponds to the outer contour of the honeycomb body in the wrapped state. To wrap the Stack or the stack around itself and around a central area ensure, the mold segments are moved towards the stack so that during the rotation of the fork-shaped entangling device of the stacks or the stacks lie against the edge of the mold segments and this edge Abutment forms. Towards the end of the manufacturing process, the shape completely closed, giving the honeycomb its final shape awarded.
Die bekannten Vorrichtungen weisen zwei Segmente auf, die geradlinig aufeinander zu und voneinander weg bewegbar sind. Während des Schließvorgangs besteht die Gefahr, daß wenigstens ein Formsegment sich gegen die Bewegungsrichtung des noch zu verschlingenden Abschnitts des Stapels bewegt. Gelangt das Formsegment gegen den Abschnitt, so kann es zu einer unerwünschten Deformation des Stapels bzw. der Stapel kommen. Eine solche Deformation kann dazu führen, daß einzelne Bleche des Stapels teilweise verbogen werden. Die Deformation der Bleche beeinflußt die Struktur des Wabenkörpers. Zum einen leidet die Festigkeit des Wabenkörpers an solchen Deformationen und zum anderen kommt es zu einer lokalen Veränderung der Kanalquerschnitte. Durch solche Veränderungen des Kanalquerschnittes wird eine ungleichmäßige Abgasverteilung durch den Wabenkörper hervorgerufen, welche die katalytische Wirkung des Wabenkörpers beeinflussen kann.The known devices have two segments that are straight are movable towards and away from each other. During the closing process there is a risk that at least one mold segment opposes one another the direction of movement of the section of the stack that is still to be devoured emotional. If the shape segment comes against the section, it can become a undesirable deformation of the stack or the stack. A such deformation can lead to individual sheets of the stack partially bent. The deformation of the sheets affects the Structure of the honeycomb body. Firstly, the strength of the honeycomb body suffers on such deformations and on the other hand there is a local one Change in channel cross-sections. Through such changes in the channel cross-section becomes an uneven exhaust gas distribution through the honeycomb body which caused the catalytic action of the honeycomb body can influence.
Die bekannten Wabenkörper sind im Querschnitt überwiegend kreisförmig ausgebildet. Die Herstellung anderer Querschnitte erfordert andere Herstellungsmethoden. Eine solche Herstellungsmethode ist z. B. durch die US-PS 4 519 120 bekannt. Nach dieser Herstellungsmethode wird zunächst ein Wabenkörper gewickelt und anschließend durch Werkzeuge deformiert. The known honeycomb bodies are predominantly circular in cross section educated. The production of other cross sections requires different production methods. Such a manufacturing method is e.g. B. by the US-PS 4,519,120. According to this manufacturing method, first a Honeycomb body wrapped and then deformed by tools.
Hiervon ausgehend liegt der vorliegenden Erfindung die Aufgabe zugrunde, die bekannte Vorrichtung und das bekannte Verfahren zur Herstellung eines Wabenkörpers so weiterzubilden, daß während des Herstellungsprozesses eine Deformation von Stapeln bzw. einzelnen Blechen vermieden wird. Ferner soll die Möglichkeit gegeben werden, Wabenkörper herzustellen, die einen nicht kreisförmigen Querschnitt aufweisen.Proceeding from this, the present invention is based on the object the known device and the known method for producing a To develop honeycomb body so that during the manufacturing process Deformation of stacks or individual sheets is avoided. Further should be given the opportunity to manufacture honeycomb bodies that one have non-circular cross-section.
Erfindungsgemäß wird diese Aufgabe durch eine Vorrichtung mit den Merkmalen
des Anspruchs 1 gelöst. Vorteilhafte Weitergestaltungen der Vorrichtung
sind Gegenstand der Unteransprüche 2 bis 5. Erfindungsgemäße
Verfahren zur Herstellung eines Wabenkörpers sind in den Ansprüchen 6
und 7 angegeben.According to the invention, this object is achieved by a device with the features
of
Die erfindungsgemäße Vorrichtung zum Herstellen eines Wabenkörpers, insbesondere eines Katalysator-Trägerkörpers, aus wenigstens einem Stapel aus einer Vielzahl von zumindest teilweise strukturierten Blechen, die eine Vielzahl von für ein Fluid durchlässigen Kanälen bilden, wobei die Vorrichtung eine an jedem Stapel angreifende gabelförmige Halteeinrichtung aufweist und Formsegmente, die sich zu einer Form schließen können, wobei jedes Formsegment jeweils einen Mantelabschnitt hat, die gemeinsam bei geschlossener Form die Außenform des herzustellenden Wabenkörpers ergeben, zeichnet sich dadurch aus, daß wenigstens zwei Formsegmente vorgesehen sind, die so verschieblich angeordnet sind, daß wenigstens ein Teilabschnitt eines jeden Mantelabschnittes am Stapel anliegend eine der Außenform entsprechende Bewegungsbahn in Richtung des jeweiligen freien Endes des Stapels beschreibt. Dadurch, daß wenigstens ein Teilabschnitt eines jeden Mantelabschnittes eine der Außenform entsprechende Bewegungsbahn in Richtung des jeweiligen freien Endes des Stapels beschreibt, wird der jeweilige mit dem Teilabschnitt des Formsegmentes in Kontakt stehende Abschnitt des Stapels derart verformt, daß im Endzustand der Formung der Stapel die gewünschte Außenform des herzustellenden Wabenkörpers erhält. Dadurch, daß die Richtung der Bewegungsbahn zum jeweiligen freien Ende des Stapels verläuft, wird eine Deformation der einzelnen Blechlagen bzw. Stapel im Gegensatz zum bisherigen bekannten Verfahren vermieden, da die Formsegmente die Abschnitte des Stapels in die endgültige Form schmiegen. In Abhängigkeit von der gewünschten Außenform des herzustellenden Wabenkörpers kann eine entsprechende Anzahl der Form segmente gewählt werden, die ein Umschlingen der Stapel bzw. einzelner Blechlagen bewerkstelligen. Vorzugsweise sind zwei Formsegmente vorgesehen, die im gleichen Richtungssinn verschieblich sind. Es ist festzuhalten, daß der Teilabschnitt des Mantelabschnittes des Formsegmentes während des Bewegungsablaufs unterschiedlicher Länge sein kann. Dies hängt zum einen von dem Bewegungsablauf des Formsegmentes und zum anderen von der Außenform des herzustellenden Wabenkörpers ab.The device according to the invention for producing a honeycomb body, in particular a catalyst carrier body, from at least one stack from a variety of at least partially structured sheets, the one Form a plurality of fluid-permeable channels, the device a fork-shaped holding device engaging on each stack and has shape segments that can form a shape, wherein each mold segment each has a jacket section that is common when the shape is closed, the outer shape of the honeycomb body to be produced result, is characterized in that at least two shape segments are provided, which are arranged so that at least one Sub-section of each jacket section adjacent to the stack one of the External shape corresponding movement path in the direction of the respective free Describes the end of the stack. The fact that at least a portion a movement path corresponding to the outer shape of each jacket section in the direction of the respective free end of the stack the respective one in contact with the section of the mold segment Section of the stack deformed such that in the final state of the formation of the Stack receives the desired outer shape of the honeycomb body to be produced. Because the direction of the movement path to the respective free end of the stack, a deformation of the individual sheet layers or In contrast to the previously known method, stacks are avoided since the Form segments nestle the sections of the stack into the final shape. Depending on the desired external shape of the honeycomb body to be manufactured an appropriate number of shape segments can be chosen that wrap around the stack or individual sheet layers. Preferably two mold segments are provided, which are in the same Direction of movement are movable. It should be noted that the subsection of the jacket section of the mold segment during the movement can be of different lengths. This depends on the one hand on the sequence of movements of the mold segment and the other from the outer shape of the honeycomb body to be produced.
Bevorzugt wird eine Ausführungsform der Vorrichtung, bei der die Formsegmente in ihrer jeweiligen Ausgangslage gegenüberliegend positioniert sind. Vorzugsweise sind die Formsegmente paarweise gegenüberliegend positioniert. Die Bewegung der Formsegmente erfolgt insbesondere synchron. Dies ist nicht zwingend erforderlich. Hinreichend ist, daß die Geschwindigkeit der einzelnen Bewegungen der Formsegmente so unterschiedlich ist, daß die Form segmente während der Herstellung des Wabenkörpers nicht gegeneinander stoßen.An embodiment of the device in which the shaped segments are preferred are positioned opposite each other in their respective starting position. The shaped segments are preferably positioned opposite one another in pairs. The movement of the mold segments is particularly synchronous. This is not mandatory. It is sufficient that the speed of the individual movements of the mold segments is so different that the Shape segments not against each other during the manufacture of the honeycomb body bump.
Gemäß einem weiteren vorteilhaften Gedanken wird vorgeschlagen, die Form so auszubilden, daß diese wenigstens ein radialein- und radialauswärts bewegliches Formsegment aufweist, welches ein Schließsegment bildet. Mit diesem Schließsegment wird im Endzustand die Form geschlossen, um dem Wabenkörper seine endgültige Form zu verleihen. According to a further advantageous idea, the shape is proposed to be designed so that these are at least one radially inward and radially outward has movable mold segment, which forms a closing segment. With this closing segment is closed in the final state in order to To give honeycomb body its final shape.

Nach diesem Verfahren wird zunächst ein Stapel aus einer Mehrzahl von zumindest teilweise strukturierten Blechen geschichtet. Der Stapel wird in eine offene Form eingebracht und in dieser von einer Halteeinrichtung in einem Zentralbereich gehalten. Die Enden des Stapels erstrecken sich von dem Zentralbereich radial auswärts. Wenigstens zwei Formsegmente werden aus ihren Ausgangslagen jeweils so verschoben, daß wenigstens ein Teilabschnitt eines jeden Mantelabschnitts zur Anlage am Stapel gelangt. Danach werden die Formsegmente so entlang einer der Außenform entsprechenden Bewegungsbahn bewegt, daß wenigstens ein Teilabschnitt eines jeden Mantelabschnittes stets in Anlage an den Stapel ist. Nachdem ein vorgegebener Umschlingungsgrad der Stapel erreicht ist, wird die Form geschlossen.According to an idea according to the invention, a method for the production a honeycomb body with a plurality of permeable to a fluid Channels from a variety of at least partially structured sheets suggested. According to this procedure, a stack is first made from a A plurality of at least partially structured sheets are layered. Of the Stack is placed in an open mold and in this by a holding device kept in a central area. The ends of the stack extend radially outward from the central region. At least two Shape segments are shifted from their starting positions so that at least a partial section of each jacket section for contact with Stack reached. Then the shape segments are along one of the External shape corresponding movement path that moves at least one Part of each jacket section is always in contact with the stack. After a predetermined degree of wrap is reached, the stack is the form closed.

Jeder Stapel wird entlang einer Knicklinie gefaltet. Die Stapel werden in eine offene Form eingebracht und in dieser von einer Halteeinrichtung in einem zentralen Bereich gehalten. Anschließend werden wenigstens zwei Formsegmente aus ihren Ausgangslagen jeweils so verschoben, daß wenigstens ein Teilabschnitt eines jeden Mantelabschnitts des Formsegments zur Anlage am jeweiligen Stapel gelangt. Die Formsegmente werden einer der Außenform entsprechenden Bewegungsbahn bewegt, so daß ein Teilabschnitt eines jeden Mantelabschnittes eines Formsegments stets am Stapel anliegt. Nachdem ein vorgegebener Umschlingungsgrad der Stapel erreicht worden ist, wird die Form geschlossen.

Die Vorrichtung weist eine gabelförmige Halteeinrichtung auf, die den Stapel
1 im Zentralbereich der Form festhält. Der Stapel 1 wird um die Dorne
13, 14 der Halteeinrichtung verschlungen. Die Form weist vier Formsegmente
2, 3, 4 und 5 auf. Sie bilden zusammen im geschlossenen Zustand eine
Form 10. Jedes Formsegment 2 bis 5 weist einen Mantelabschnitt 6, 7, 8
und 9 auf, die gemeinsam bei geschlossener Form 10 eine Außenform 15
des herzustellenden Wabenkörpers ergeben. The device has a fork-shaped holding device which holds the
Die Formsegmente 3 und 5 sind radialein- und radialauswärts verschieblich
angeordnet.The
In der Fig. 2 sind die Formsegmente 2 und 4 zur Anlage an den Stapel 1
gebracht worden. Der Teilabschnitt 11 des Mantelabschnitts 6 des Formsegments
2 bzw. der Teilabschnitt 12 des Mantelabschnitts 8 des Formsegments
4 liegt an dem Stapel 1 an. Der von dem Dorn 14 bzw. 13 aus der Form
herausragende Abschnitt des Stapels ist entsprechend der Krümmung des
Teilabschnittes 11 bzw. 12 umgebogen. In der Fig. 3 ist die Position der
Formsegmente 2 und 4 dargestellt, die sie einnehmen, wenn eine 30°-Drehung
der Formsegmente 2 und 4 vollzogen worden ist. Während der
Drehung in der Pfeilrichtung R wurde ein weiterer Abschnitt des Stapels
verformt. Die Drehung der Formsegmente 2 und 4 erfolgte dabei so, daß
der Teilabschnitt 11 bzw. 12 des Formsegments 2 bzw. 4 stets am Stapel
anlag. Durch eine weitere Drehung der Formsegmente 2 und 4 nehmen
diese eine Position, wie sie in der Fig. 4 dargestellt ist. Die Formsegmente
2 und 4 sind dabei um 90° gegenüber ihrer ursprünglichen Lage verdreht
worden. Wie besonders aus der Fig. 4 ersichtlich ist, ist der Teilabschnitt
11 bzw. 12 des Mantelabschnitts 6 bzw. 8 wesentlich größer als in den
Fig. 2 und 3 ersichtlich ist. Durch eine weitere Verschiebung der Formsegmente
3 und 4 wird der Stapel in seine endgültige Form gebracht. In dem
dargestellten Ausfiihrungsbeispiel ist eine Drehung der Segmente 2 und 4 um
